To determine if angles e and f are adjacent, we need to check if they share a common ray and a common vertex.

  1. Common Vertex: Both angles e and f emerge from the same point where the rays originate, so they share a common vertex.

  2. Common Ray: The angle labeled e is formed by the two leftward rays, whereas the angle labeled f involves one of those rays and the vertical line. If both angles share one of the same rays (the ray that is part of angle e and the vertical line forming angle f), then they share a common ray.

Based on this reasoning, the correct response is:

Yes, they share a common ray.
